Here's the question you clicked on:

When finding the limit using l'Hôpital's rule and you eliminate the denominator, can you continue to derivate?
If l'Hopital's Rule applies, yes. When does it apply? When you have an indeterminate form (0/0 or infty/infty). Hope that helped!
thank you! yeah, i did the whole question, i just wanted to know if i could continu to derivate :)
I'm glad I could help! Thanks for the medal. :)
